Designed for standalone applications, the Siemens QRH22B200L delivers essential thermal-magnetic protection for commercial systems. This 2-pole unit-mount MCCB from the SENTRON family features fixed long-time and instantaneous (LI) trip functions. Unlike bolt-on models, it utilizes line and load lugs, making it ideal for individual enclosures. It serves as an exact cross-reference replacement for older QJ22B200 lug-style breakers. Delivering 25kAIC at 240VAC, the unit is also HACR rated.

Product FAQs
6 answers
Does the QRH22B200L replace older Siemens QJ frame breakers?
Yes, the Siemens QR frame is the direct replacement for the discontinued QJ frame. The QRH22B200L can replace legacy QJ22B200 breakers in standalone enclosures, offering the same form and fit with upgraded features.
What does the L at the end of the QRH22B200L catalog number indicate?
The L indicates that the breaker is supplied with both line and load side lugs installed. This configuration is required for individual enclosure mounting and standalone applications.
Can the Siemens QRH22B200L be reverse fed?
Yes, this molded case circuit breaker is UL listed for reverse feed applications, allowing flexibility in how it is wired within a panel or enclosure.
What is the difference between the QR22B200 and the QRH22B200L?
The H in the QRH22B200L designates a higher interrupting capacity. While the standard QR22B200 is rated for 10kA at 240V, the QRH22B200L provides a 25kA interrupting rating at 240V.
Can I add field-installable accessories to the QRH22B200L?
Yes. Unlike the legacy QJ series, the Siemens QR frame supports field-installable internal accessories. You can easily add shunt trips or auxiliary switches on site without ordering a custom factory build.
Is the QRH22B200L suitable for HVAC equipment?
Yes, this circuit breaker is HACR rated, meaning it is tested and approved for use with heating, air conditioning, and refrigeration equipment.
